I caught my wife going to her coworkers house at 4:30 in the morning right before I got out of work — after I told her I don’t want her contacting him. Well I thought it was all good.
For some reason, I left my phone in car while I was at work. And the recorder was on. I asked her what she did after work, she said take a shower then to get me. Well she went to his house — I could hear them talking for a bit about going inside his house. They did for about 20 minutes, then got back in car, and I heard them saying they hope I don’t sneak up on them talking behind my back. I mean, she cheated. What do you think?

I think you need to talk to a marriage counselor, because there is too much going on that you haven’t told us in two paragraphs. Also no one “for some reason I left my phone and the recorder on.” You did that to check up on her, because you don’t trust her. There is no “oops I left the recorder on” part of the phone. Come on now. In this day and age everyone knows how a cell phone works and that they go to sleep after a set amount of time unless you turn that off.
Agreed. “Oops, I left my phone recorder on” is sketchy as hell …
